What Is CMMC and Why Does It Matter?

The Cybersecurity Maturity Model Certification (CMMC) is the DoD's mandatory cybersecurity framework for the Defense Industrial Base. Under DFARS 252.204-7021, every defense contractor that handles Federal Contract Information (FCI) or Controlled Unclassified Information (CUI) must achieve and maintain the required CMMC level before being eligible to bid on, win, or retain DoD contracts.

CMMC 2.0 replaced the original five-level model with a streamlined three-level framework built on NIST SP 800-171. Unlike the previous self-attestation model under DFARS 252.204-7012, Level 2 now requires a mandatory third-party assessment by an accredited C3PAO — which means you can no longer simply check boxes on a spreadsheet and call it done.

Most defense contractors underestimate how much CUI they actually handle. Contract drawings, program schedules, technical data packages, and even routine email threads referencing part numbers can all qualify as CUI under the National Archives registry. Once CUI enters your environment, all 110 NIST SP 800-171 controls are in scope. Scoping your CUI enclave correctly is the single most impactful step you can take before starting remediation.

CMMC 2.0 is now embedded in DoD solicitations across all phases of the final rule. Contractors who cannot demonstrate compliance at award are not eligible to bid — regardless of past performance or incumbent status.

Who Needs CMMC Compliance?

Any company in the Defense Industrial Base that processes, stores, or transmits FCI or CUI in performance of a DoD contract is subject to CMMC requirements — prime contractors and subcontractors alike.

Prime Contractors

If you hold a DoD prime contract, CMMC clauses are flowing into your new awards now. You are also responsible for ensuring your entire supply chain meets the applicable level.

  • Level 2 C3PAO assessment required for most CUI-handling primes
  • Must flow CMMC requirements down to all subcontractors
  • SPRS score must reflect actual system security plan
  • Annual affirmation required for self-attest programs

Subcontractors & DIB Suppliers

CMMC requirements flow down from primes to all tiers. If you receive FCI or CUI under a prime contract, you are subject to the same requirements as your prime — even if you are a small business.

  • Flow-down clauses in subcontracts require CMMC compliance
  • Primes are refusing awards to suppliers without a compliant posture
  • Non-compliance is grounds for contract termination
  • Same C3PAO assessment standards apply regardless of size

IT & MSP Providers

Managed service providers, cloud providers, and IT vendors that operate, maintain, or have access to systems processing CUI on behalf of a defense contractor are also in scope for CMMC.

  • External service providers may be assessed as part of the contractor's boundary
  • Cloud services must meet FedRAMP Moderate or equivalent
  • Access to CUI systems requires equivalent security controls
  • Flow-down to IT providers is a common oversight

CMMC 2.0 Levels Explained

The level you need is driven by the type of information you handle under your DoD contracts. Here is how CMMC 2.0 breaks down.

Level 1

Foundational

  • 17 basic cybersecurity practices
  • Applies to contractors handling FCI only (no CUI)
  • Annual self-attestation by a senior company official
  • Based on FAR 52.204-21 requirements
  • No third-party assessment required
  • Lowest barrier — start here if you handle only FCI
Level 2

Advanced

  • 110 practices aligned to NIST SP 800-171
  • Applies to all contractors handling CUI
  • Third-party C3PAO assessment required for most contracts
  • Self-attestation only for non-prioritized programs
  • Triennial assessment cycle
  • The standard for the vast majority of the DIB
Level 3

Expert

  • 110+ practices including NIST SP 800-172 controls
  • Applies to contractors on named DoD priority programs
  • Government-led assessment conducted by DCSA
  • Reserved for highest-value, highest-sensitivity programs
  • Builds on full Level 2 compliance
  • Relatively small percentage of DIB

Our CMMC Compliance Services

End-to-end CMMC consulting for defense contractors at every stage — from initial gap assessment through C3PAO certification and ongoing managed compliance.

Gap Assessment

A full review of your environment against all 110 NIST SP 800-171 controls, with a documented SPRS score, a CUI inventory, and a prioritized remediation roadmap. Your gap assessment is the foundation everything else builds on.

Readiness Assessment

A mock C3PAO assessment that mirrors the official CMMC assessment methodology. We collect objective evidence, run through interview questions, and identify every gap before your actual assessment so nothing surprises you on audit day.

Policy & Documentation

System Security Plan (SSP), Plan of Action and Milestones (POA&M), incident response plan, and the full supporting policy library — authored in plain English and tailored to how your business actually operates, not a generic template.

Technical Controls Implementation

Network segmentation, FIPS-validated encryption, multi-factor authentication, audit logging, vulnerability management, and endpoint hardening across your in-scope environment. We implement, not just advise.

Managed Compliance

Ongoing log review, vulnerability scanning, quarterly evidence refresh, and annual SSP updates so your CMMC posture holds between assessments. Our 24/7 Managed SOC keeps your environment continuously monitored and documented.

C3PAO Certification Support

Scoping, scheduling, evidence packaging, interview coaching, and on-site support during your formal C3PAO assessment. We prepare you for your CMMC assessment so your business passes the first time.

How We Get You to CMMC Certification

A proven, fixed-scope engagement model built around how defense contractors actually operate — not a generic consulting framework.

1

Scope & Gap Assessment

We identify every system, user, and data flow that touches CUI, define the boundary of your CMMC environment, and assess your current posture against all 110 controls. You receive a scored gap report and an SPRS score you can stand behind.

2

Remediation Roadmap

We prioritize gaps by risk and complexity, build a realistic timeline that fits your contract obligations, and assign clear ownership for every remediation action. No 200-item checklist with no order — a sequenced plan your team can execute.

3

Policy & Technical Remediation

We write your SSP, POA&M, and supporting policies, then implement the technical controls — MFA, network segmentation, FIPS encryption, audit logging, endpoint hardening — across your in-scope environment. We do the work, not just advise on it.

4

Assessment Support

We run a full mock C3PAO assessment against the official methodology, close any remaining gaps, package your evidence, and coach your team for interview questions. Then we stand alongside you during your formal assessment.

5

Ongoing Managed Compliance

CMMC certification is not a one-time event — it requires continuous maintenance. Our managed compliance program keeps your documentation current, your controls operative, and your posture audit-ready between triennial assessments.

Why Defense Contractors Choose Telco United

CMMC-Focused, Not CMMC-Adjacent

We specialize exclusively in CMMC and defense contractor cybersecurity. Our team understands DFARS 252.204-7012, the CMMC Assessment Process (CAP), and how C3PAOs evaluate evidence — not just general security frameworks.

Fixed-Price Engagements

Every engagement is scoped and quoted fixed-price before work begins. You know the cost before you commit, and scope changes require your approval. No hourly billing surprises when remediation takes longer than expected.

We Implement, Not Just Advise

Most consultants deliver a gap report and leave. We stay through remediation — writing policies, configuring systems, and implementing controls — so your team is not left translating recommendations into action on their own.

Small & Mid-Size Contractor Focus

We work with defense contractors that have 10 to 500 employees. We know how to right-size the CUI enclave so you are not rebuilding your entire IT infrastructure, and how to leverage cloud-based FedRAMP solutions that fit a small-business budget.

Frequently Asked Questions

What is CMMC compliance?
CMMC (Cybersecurity Maturity Model Certification) is the DoD's mandatory cybersecurity framework for defense contractors. It requires companies that handle Federal Contract Information or Controlled Unclassified Information to achieve a verified level of cybersecurity practice before they can bid, win, or retain DoD contracts. Level 2 — which covers most CUI-handling contractors — requires a third-party assessment by an accredited C3PAO.
Does my company need CMMC if we are a subcontractor?
Yes. CMMC requirements flow down through the entire supply chain. If your prime contractor holds a DoD contract with CMMC clauses, they are required to flow those requirements to you as their subcontractor. Any company that handles FCI or CUI — at any tier — must meet the applicable CMMC level. Non-compliance is grounds for termination of the subcontract.
What is the difference between CMMC Level 1 and Level 2?
Level 1 covers 17 basic practices from FAR 52.204-21 and applies to contractors handling FCI but no CUI. It is self-attested annually with no third-party assessment. Level 2 covers all 110 controls from NIST SP 800-171 and applies to contractors handling CUI. Level 2 requires a formal third-party assessment by an accredited C3PAO every three years for most contracts. The vast majority of defense subcontractors fall under Level 2.
How long does CMMC compliance take?
Most small to mid-size contractors need six to nine months to reach CMMC Level 2 readiness from a standing start — including gap assessment, remediation, policy writing, technical controls implementation, and pre-assessment review. Scheduling and completing the formal C3PAO assessment adds another two to four months. Starting early is critical given the assessor backlog at accredited C3PAOs.
What is the difference between CMMC and NIST SP 800-171?
NIST SP 800-171 is the technical standard — 110 security controls in 14 families. CMMC Level 2 is built directly on NIST SP 800-171 but adds mandatory third-party verification. Under DFARS 252.204-7012, companies could self-attest compliance. CMMC removes that option for most CUI-handling contractors and requires a C3PAO to verify your controls independently.
What does CMMC compliance cost?
Most contractors with 25 to 100 employees spend $60,000 to $150,000 reaching Level 2 readiness, plus $2,000 to $6,000 per month for ongoing managed compliance, plus the C3PAO assessment fee. Actual cost depends on your current posture, the size of your CUI enclave, and how many gaps exist at the start. Telco United quotes all work fixed-price so there are no billing surprises.
